SPECIFEGATION forming part of Letters Patent No. 689,944, dated December 31, 1901.

Application filed February 15,1900. Renewed May 1, 1901. Serial No. 58,361. (No model.)

To all whom it ntcty concern:

Be it known that I, CHARLES Annnnws, a citizen of the United States, and a resident of South Bend, St. Joseph county, State of Indiana, have invented certain new and useful Improvements in Sprinkler-Heads, of which the following is a specification.

This invention relates to sprinklers and such as are especially adapted for use in sprin- 1o kling roadways and flushing the gutters thereof.

The object of the invention is to provide a simple, convenient, and efficient sprinklerhead; and the invention consists of the features and combinations of features hereinafter set forth, and more particularly pointed out in the claims.

In the drawings forming part of this specification, and in which like numerals designate corresponding parts, Figure 1 is a side elevation of a sprinkling-wagon with parts omitted and broken away, having attached thereto a sprinkling-head embodying the invention. Fig. 2 is a side elevation with the sprinklerz 5 head detached,with the flushing-outlet turned upward. Fig. 23 is a sectional elevation on the line 3 3 of 2. Fig. 4 is a view simi lar to Fig. 3 and showing a modification. Fig. 5 is a detached side elevation of a modified form of sprinkler-head and partly broken away. Fig. 6 is a View similar to Fig. 5 and modified in one particular.

Referring now more particularly to the particular embodiments of the invention illus- 3 5 trated in the drawings, 1 is a casting, generally made of iron, having an inlet 2 at its inner end connected with the hose-pipe 3, which leads from the reservoir 4.

5 is a hanger to which the casting 1 is re- 0 movably attached,the latter having slots 6, de-

signed to receive bolts carried by the hanger 5;

The cylinder 7, which is bolted to the casting 1, is provided with suitable spray-outlets and also with a suitable gutter-flushing out- 5 let. The spray-outlets may be in the form of slots or in the form of rows of perforations, as desired. They are preferably arranged circumferentially of the cylinder and in numerous lines and are graduated in size, their size increasing toward the upper side of the cylinder 7.

S is a shield or cover adapted to slide circumferentially on the cylinder to cover and uncover the spray-outlets, its chief function being to close more or less (circumferentially of the cylinder) of the spray-outlets, as when the sprinkling-wagon is passing a vehicle in the road. The shield 8 slides between the split ring 9 and a lip formed on the flange 10 of the cylinder. It is operated from the drivers seat bya system of rods and levers 11, 12,13, and 1a.

The flushing-outlet 15 is arranged beyond the position of the spray-outlets and is designed for use in flushing gutters or other parts of a roadway or in. similar situations Where a full stream is desired instead of a spray. The spray-outlets and the guttcrflushing outlet are both controlled by a piston, of which 16 is the cylindrical piston-head.

having washers 17, and which piston-head is fixed on the piston-rod 18. The piston reciprocates within the cylinder. The end wall 19 of the cylinder is centrally apertured to afford one bearing for the piston-rod, the other hearing being formed on the bracket 20. The inner end of the rod may project into the recess 21. The piston-head need not fit the walls of the cylinder very tightly. A valveseat is employed, which is located on the tank side of the cylinder-outlets, and against this valve-seat the piston-head, acting as a valve, closes toshut off entirely the outflow of the water. This valve-seat is numbered 36, and, as shown in Figs. 3 and 4, it may be formed at the inner end of the cylinder. It may of course be located at any convenient place on the inlet or tank side of the cylinder-outlets. By reason of the use of such a piston-valve and valve-seat it is not necessary to depend on the circumferentially tight fit of the piston-head in the cylinder for the shutting off of the outflow of water, and hence the pistonhead need not fit the walls of the cylinder very tightly, and the piston can be operated with less power and with less wear upon the circumference of the piston-head and interior of the cylinder, and, moreover, the outflow of water can be shut off with less liability of leakage. I prefer to construct the outer part of the cylinder with a slightly-enlarged interior 22, so that when the sprinkler is not in use the piston-head may be drawn to that part of the cylinder and the circumferential packing thereby be preserved from deterioration, while the piston as a whole and its head and connected parts remain within the cover and protection of the cylinder and without withdrawing the piston from the cylinder. In the construction herein shown in Figs. 2, 3,and 4 this enlarged portion is also that portion of the cylinder in which the flushing-outlet 15 is placed. The entire cylinder is shown in Fig. t to be formed of one piece of metal. I prefer, however, to form that portion of the cylinder which constitutes or includes the gutter-flushing outlet 15 of a separate piece of metal from the rest of the cylinder, as shown in Fig. 3, arranging it for circumferential adjustment in order that the radial direction of the gutter-flushing outlet may be controlled. For this purpose in the particular construction shown in Fig. 3 the end part 22 of the cylinder is provided at its inner end with a split ring 24:, having internal threads, so that it may be screwed onto the other part of the cylinder. A screw 25 passes through the projecting ends of the split ring 24 for the purpose of locking it firmly in any particular desired position. By loosening the split ring by means of screws 25 the part 22 of the cylinder may be rotated into the circumferential position desired or into the longitudinal position desired and there locked firmly and immovably again to the rest of the cylinder. In Fig. 1 the gutter-flushing outlet opens downward. In Fig. 2 it opens upward. It is of advantage to have the gutter-flushing outlet adjustable and of particular advantage to have it circumferentially adjustable, be-

cause in some cases it is desirable to throw the flushing-water directly downward, as into a gutter or in a particular part of the roadway, and in other cases it is desirable to throw the flushing-water to one side or the other at one angle or another or even directly upward.

The gutter-flushing outlet may be of any size desired both longitudinally and circumferentially of the cylinder. In Fig. 5 it is shown at 28 as one hundred and eighty degrees long circumferentially and as somewhat narrow or contracted longitudinally of the cylinder. In Fig. 6 it is similarly shown at 29. In Figs. 1 to 4 it is shown at 15 as of the same circumferential length of one hundred and eighty degrees, but as somewhat broader or larger longitudinally of the cylinder. In Figs. 1 to 4 also the gutter-flushing outlet is shown as enlarged by the removal of the outer part of a sector of the end wall 19 of the cylinder; but this is not essential orimportant, as it merely reduces the weight and cost of the parts. Figs. 5 and 6 differ in that the end 26 of the cylinder in which the flushing-outlet is constituted in Fig. 5 is formed of a separate piece of metal from the rest of the cylinder, so as to afford adjustability to the flushing-outlet, whereas in Fig.

ceases 6 the end 27 is formed integral with the rest of the cylinder.

3O designates the outer end wall of the cylinder 37 in Fig. 5.

31 designates the outer end wall of the cylinder 38 in Fig. 6.

The piston is worked from the drivers seat through the system of rods and levers 32, 33, 34:, and 35.
